SEMTECH UCLAMP0501P.TCT 瞬态抑制二极管(TVS)产品概述

一、产品核心身份识别

UCLAMP0501P.TCT是SEMTECH推出的单向瞬态抑制二极管(TVS),专为低电压系统的瞬态过压防护设计。该器件采用SLP1006P2小型贴片封装,单通道结构,可快速响应静电放电(ESD)、电快速瞬变脉冲群(EFT)等瞬态干扰,保护敏感电子电路免受不可逆损坏。

二、关键电气参数解析

UCLAMP0501P.TCT的参数针对5V供电系统优化,核心指标如下:

  1. 反向截止电压(Vrwm):5V,即器件正常工作时反向偏置不导通的最大电压,与被保护电路的工作电压精准匹配;
  2. 击穿电压(Vbr):9V(典型值),是器件开始导通的电压阈值,确保瞬态干扰超过此值时快速响应;
  3. 钳位电压(Vc):12.5V(@8/20μs脉冲),导通后将瞬态电压钳位至安全值,远低于敏感电路的损坏阈值;
  4. 峰值脉冲电流(Ipp):16A(@8/20μs),可承受的最大瞬态脉冲电流,覆盖典型ESD/EFT冲击强度;
  5. 峰值脉冲功率(Ppp):200W(@8/20μs),反映器件的瞬态能量吸收能力;
  6. 反向漏电流(Ir):5μA(最大),正常工作时漏电流极小,不影响被保护电路功耗;
  7. 结电容(Cj):160pF,结电容适中,平衡防护性能与信号完整性(适合低/中频电路)。

三、瞬态干扰防护能力

该器件符合国际防护标准,可有效应对两类核心干扰:

  1. 静电放电(ESD)防护:满足IEC 61000-4-2标准,可承受人体模型(HBM)、机器模型(MM)等典型ESD冲击,避免设备因静电失效;
  2. 电快速瞬变脉冲群(EFT)防护:符合IEC 61000-4-4标准,抑制快速脉冲群对电路的干扰,提升系统抗干扰性;
  3. 单向防护特性:仅对反向瞬态过压(对应TVS反向击穿机制)进行抑制,适合单方向信号/电源端口的防护需求。

四、封装与可靠性设计

  1. SLP1006P2封装:小型贴片封装(尺寸紧凑,适配高密度PCB布局),无铅无卤,兼容回流焊工艺;
  2. 宽温工作范围:结温(Tj)覆盖-55℃~+125℃,满足工业级、汽车级等严苛环境温度需求;
  3. 长期稳定性:低漏电流、高抗脉冲能力确保多次瞬态冲击后性能稳定,延长系统使用寿命。

五、典型应用场景

因低电压匹配、小封装等特点,UCLAMP0501P.TCT广泛应用于:

  1. 便携式电子:手机、平板、智能手表的USB接口、充电端口防护;
  2. 物联网终端:传感器节点、智能家居设备的低电压信号端口防护;
  3. 工业控制:PLC、传感器模块的5V供电/信号端口ESD/EFT防护;
  4. 消费电子:蓝牙耳机、智能音箱的接口与电源端防护。

六、合规与标准认证

该器件满足多项国际要求:

  • 瞬态防护:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT);
  • 环保:符合RoHS、REACH无铅无卤标准;
  • 可靠性:通过温度循环、湿度测试等验证,适合量产应用。

UCLAMP0501P.TCT凭借精准的电压匹配、可靠的防护性能及小封装设计,成为低电压系统瞬态防护的优选器件。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
